Sometimes it works, sometimes it doesn't. The mirror appears to be working correctly at all times and when the H.U.D works, the dimmer control seems to work fine and all is bright. I've read about the seemingly common fading in and out issue but this appears to be different. Ideas on what I can check? I haven't had a chance to get a wiring diagram and check basic power/grounds yet but the mirror adjustment does work fine. Ideas? Fairly easy to remove and check solder connections?
